MAX621CPN

Overview

The MAX621CPN is a high-side gate driver IC designed for controlling N-Channel MOSFETs. It incorporates four MOSFET drivers and an integrated charge-pump high-side power supply to enable high-side switching and control. The device features non-inverting logic compatible with CMOS and TTL inputs. It operates with a maximum power dissipation of 640 mW and draws an operating supply current of 500 uA. The component is housed in an 18-PDIP package and supports through-hole mounting.

Feature Summary

• Integrates four MOSFET drivers with a dedicated charge-pump high-side power supply
• Provides non-inverting signal control for N-Channel MOSFETs
• Supports standard CMOS and TTL input logic levels

Applications

• High-side switching control circuits
• Power management systems requiring N-Channel MOSFET drive
• Industrial motor control interfaces

Procurement Notes

Verify the specific suffix 'CPN' confirms the 18-PDIP through-hole package and commercial temperature range. Confirm active status with the manufacturer, as availability may vary by region. Ensure input voltage levels match the specified CMOS/TTL compatibility before integration into the design.

Selection Notes

Select this component when a compact solution for driving multiple high-side N-Channel MOSFETs is required without external bootstrap circuitry. The integrated charge pump simplifies board layout compared to discrete driver solutions. Verify that the 640 mW power dissipation rating accommodates the thermal requirements of the specific application environment.

Part Context

This part belongs to the MAX620/MAX621 family of gate drivers. These devices are engineered to simplify the interface between low-voltage logic controllers and high-voltage power stages. The series is commonly utilized in applications requiring reliable high-side switching capabilities within a single integrated package.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX620/MAX621 family or newer Analog Devices gate driver portfolios. Ensure any substitute maintains the four-driver configuration and integrated charge-pump functionality.
